To all whom it may] concern: V

Beit known that LED ARD BELLAVANQE, Jr., citizen of the United States,residing at Moosup, in the county of Windham and State of Connecticut,have invented or discovered certain new and useful Improvements inMachines for Straightening Loom- Shuttles, of which the following is aspec1fi cation, reference being had therein tothe accompanying drawings,

This invention relates to a machlne vfor straightening up the sides ofloom shuttles when they'have become worn or 'rounde'd'in use. V

To this end the invention comprises a holder for the shuttle whichisadapted to be reciprocated v in proximity to a rotary, grinding disk,as will hereinafter more fully.

appear.

In the accompanying drawings Figure 1. 'is an end view, with partsbroken awayin vertical section, of the lmprovedrmach ne, I

and Fig. 2 is a plan view of the same.

Referring to the drawings, a denotes a framework or table mounted onsuitable standards or legs I). Attachedtothe framework or table a is abracket a affording bearings for a driving shaft 11 to the inner end ofwhich is attached a grinding disk c rotatlng in an opening in the saidframework or table a,the working face of said grooved pulley Z,

disk being covered with sand paper or other abrasive material glued orotherwise suitably attached thereto.

The shaft 71 is provided with a loosepulley p, a fast or driving pulley0 and a I Said shaftz' is slidingly mounted in its bearings in thebracket-a so that it may be adjusted endwise through the pulleys Z, 0and 79, but the said pulleys Z and 0 are connected thereto, so as torotate there with, by means of a spline i. Extending upward from theframework or table a is a standard a from which extends laterally a rodh supporting a belt guide it which is slidingly mounted on said rod sothat it may be adjusted by means of a handle 71? to shift a driving beltfrom the fast pulley 0 to the loose pulley p, or vice versa.

Mounted to reciprocate on the framework or table a is a slide d whichmay be guided in any suitable manner on saidframework, or table, as bybeing provided on its under side with ribs or projections 25 enteringslots d" Specification of Letters Patent. i Patented-NOV, 30, 1915,Application filed July 28, 1915.

said blocks 6 being overlaid by plates 7 beneath the heads g of thescrews 9 so that the said plates, in connection with said blocks 6,willservewto hold a shuttle se curely to the'slided with'theside of suchshuttle in contact with the grinding disk 0. The slide (l and theshuttle-holding parts, just described, mounted thereon, constitute ashuttle holder or carrier to cooperate with the grinding or abrasivedisk 0. i v The'diskc maybe adjustedvto bring it into suitable workingcontact with a shuttle held on the shuttle-carrying slided by means ofan adjusting screw 9 tapped inv the bracket a and having a swiveledconnection with a-bar n attached to'one end of the shaft 2' by a screw71/, the shaft being maint'ained in any desired position of adjustmentbymeans of a set screws one end of which abuts againstthe bracket 0/. 1The pulley Z is connected by a belt with a large pulley '70 on a shaft jsuitably journaled in a support on the framework of the Vmachine andprovided at its inner end with a disk carrying a crank u joined by aconnecting rod 15 withone of the projections 2) extending downwardfromthe slide d, so that by the rotation of the said shaft j the said slidewill be reciprocated back and forth relative to the framework or table'a.

From the foregoing it will be understood that when a shuttle to bestraightened is mounted on the reciprocating slide (Z and versed in itsholder and'the other side therer of beoperated on to grind andstraighten the same. In this operation of the machine the shaft z may beadjusted endwise by means of the screw 9, as circumstances may require,to bring the grinding disk c into properrelationto the shuttle beingstraight ened.,

The invention is not to be understood as being limited tothedetailsherein shown and described, as these may be varied widely,

within the limits of mechanical skill, without departing from the scopeof the invention.

Having thus described my invention- I claim and desire to secure byLetters Patent:
